[0002] The existing carbon monoxide detection in flue gas is generally performed by installing a special carbon monoxide monitoring instrument on a flue gas pipeline or using a handheld carbon monoxide detector to detect at a flue bypass.

[0003] The carbon monoxide detector: the working temperature range is usually less than 50 DEG C, and it cannot be used in a flue gas environment higher than 50 DEG C, resulting in that the installation position of the CO detector is very limited.

[0004] The handheld carbon monoxide monitor: only the CO concentration in the environment can be monitored, the CO concentration in the flue gas pipeline cannot be detected, and real-time monitoring cannot be achieved.

[0005] The above two commonly used CO detection instruments cannot detect the CO concentration of high-temperature flue gas in the pipeline in real time; even if the CO concentration can be detected, the single detection data cannot be used as a research method to analyze the CO concentration and the catalytic conversion efficiency of CO; meanwhile, these CO detection instruments cannot provide flue gas flow, temperature and pressure data, and do not have the function of analysis and test.
